Description

Technical Field

[0001] The invention belongs to the field of seed seedling cultivation, and in particular relates to a method for improving the germination rate of broad-leaved fig. Background Art

[0002] Ficus microcarpa, also known as five-fingered hairy peach and five-dragon root, is a small woody shrub of the genus Ficus in the Moraceae family. It is oblong-ovate or broadly ovate with fine serrations. Its figs are borne in pairs in the axillary branches or on deciduous branches, and are spherical or oval-spherical. Its leaves are five-branched, hairy, and fragrant. It is primarily produced in Guangdong, Hainan, Guangxi, Fujian, and Yunnan provinces. It often grows under or at the edge of forests, with an optimal altitude of 180-1380 meters. Its flowers bloom year-round, with a small number of fruits in the inflorescence and a short reproductive cycle, making it easy to form natural populations. It has a long history of medicinal use and is a common herbal remedy in South China. It is effective in treating myasthenia gravis and pediatric cough and asthma. Its dried roots are used to strengthen the spleen and lungs, and to relieve dampness and relax the muscles.

[0003] When raising seedlings of existing Ficus microcarpa, the seeds are usually evenly spread on the seedling medium and then sprinkled with sufficient water. However, due to the uneven quality of the seeds, the germination rate of Ficus microcarpa is obviously graded, and even some poorly developed seeds will affect the normally developed seeds. Therefore, it is necessary to propose a method to improve the germination rate of Ficus microcarpa. Summary of the Invention

[0004] The invention aims to provide a method for improving the germination rate of a thick-leaved ficus. The method comprises the following steps: applying a transverse driving force and a longitudinal driving force to the thick-leaved ficus seeds according to the weight of the seeds, changing the sedimentation rates of the thick-leaved ficus seeds in different time periods, and thereby performing classification and seed selection on the thick-leaved ficus seeds. Since the weights of the seeds passing through different chambers are different, the heavier seeds may be larger, fuller, or have more complete internal development, while the lighter seeds may be smaller or have empty shells. Therefore, the seeds with a high sedimentation rate have the best quality and the highest germination rate, while the seeds with a low sedimentation rate have a poor germination rate. The seeds with a high sedimentation rate and the seeds with a low sedimentation rate are separated and concentrated for cultivation. The seeds are dropped into a matrix more evenly, thereby further improving the seed germination rate. Cultivating seedlings in this manner reduces grading, focuses on cultivating seeds with a high sedimentation rate, further improves the germination rate, and reduces labor costs.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows: a method for improving the germination rate of Ficus microcarpa, comprising the following steps:

[0006] Step 1: Spread fresh Ficus microcarpa seeds evenly and dry them in the sun; select seeds after drying;

[0007] Step 2: Soak the selected Ficus microcarpa seeds with 1-1.5% carbendazim and dry them for later use;

[0008] Step 3: Mix peat soil and nutrient soil in a volume ratio of 1-2:1-2 and set aside;

[0009] Step 4: According to the different weights of the Ficus microcarpa seeds, a lateral driving force and a longitudinal driving force are applied to the Ficus microcarpa seeds to change the sedimentation rate of the Ficus microcarpa seeds in different time periods, thereby classifying and selecting the Ficus microcarpa seeds; and then the Ficus microcarpa seeds are evenly spread on the seedbed.

[0010] The above solution achieves the following principles and beneficial effects:

[0011] The method comprises the following steps: spreading fresh Ficus microcarpa seeds evenly and airing them in the sun, and selecting seeds after airing; screening out seeds containing impurities, diseases, insects, mildew and defects, and selecting seeds without insect holes and defects; soaking the selected Ficus microcarpa seeds in 1.5% carbendazim, and air-drying them for later use; mixing peat soil and nutrient soil in a volume ratio of 1:1 and setting them aside; applying lateral and longitudinal driving forces to the Ficus microcarpa seeds according to their weights, and changing the sedimentation rates of the Ficus microcarpa seeds in different time periods, thereby classifying and selecting the Ficus microcarpa seeds; and then spreading the Ficus microcarpa seeds evenly on a seedbed.

[0012] The invention applies a transverse driving force and a longitudinal driving force to the broad-leafed ficus seeds according to the different weights of the broad-leafed ficus seeds, changes the sedimentation rates of the broad-leafed ficus seeds in different time periods, and thus classifies and selects the broad-leafed ficus seeds. Since the weights of the seeds passing through different chambers are different, the heavier seeds may be larger and fuller, or have more complete internal development, while the lighter seeds may be smaller or have empty shells. Therefore, the seeds with a high sedimentation rate have the best quality and the highest germination rate, while the seeds with a low sedimentation rate have a poor germination rate. The seeds with a high sedimentation rate and the seeds with a low sedimentation rate are separated and cultured collectively. Furthermore, the seeds are dropped into a matrix more evenly, thereby further improving the seed germination rate.

[0013] Furthermore, in step 1, 7 days before sowing, the seeds of Ficus microcarpa were evenly spread and air-dried for 48 hours, and were turned over every 6 hours.

[0014] Beneficial effects: 7 days before sowing, evenly spread and air-dry the seeds of Ficus coarse-leafed fig for 48 hours, turning them over every 6 hours; this allows each seed to receive sufficient light to kill pathogenic bacteria on the surface of the seeds, while breaking the dormancy period of the seeds, stimulating seed activity, and increasing the germination rate of the seeds.

[0015] Furthermore, in step one, when selecting seeds, seeds containing impurities, diseases, insects, mildew and defects are screened out, and seeds without insect holes and defects are selected.

[0016] Beneficial effect: Seeds with impurities, diseases, insects, mildew and defects are first selected by visual inspection to reduce the complexity of subsequent operations as much as possible.

[0017] Furthermore, it also includes a sprout-promoting device, which includes a shell, a seedling bed is provided below the shell, and the seedling bed is fixedly connected to the shell through a plurality of brackets;

[0018] The side wall of the shell is connected to a first tube, and the top of the first tube is connected to a second tube; the side wall of the shell away from the first tube is connected to a fourth tube;

[0019] A plurality of baffles are fixedly connected to the bottom wall of the shell, and the baffles divide the upper part of the shell into a first cavity, a second cavity, and a third cavity from right to left. A plurality of symmetrically arranged boxes are installed in the first cavity, the second cavity, and the third cavity, and the tops of the boxes are all inclined. The gaps between adjacent boxes form a channel. A first opening is opened on the side wall of the box near the channel, and an electric push rod is installed in the box. The output shaft of the electric push rod passes through the first opening and is coaxially fixedly connected to the arc plate. When the adjacent arc plates are closed, they are used to close the channel.

[0020] A water spray assembly is provided at each channel; a shaking assembly for shaking seeds is provided below each water spray assembly; a plurality of second openings for seeds to pass through are provided at the bottom of the shell; and the seedbed is located below the plurality of second openings.

[0021] Beneficial effects: The electric push rod is started, and the electric push rod pushes the two arc-shaped plates to move toward each other to close the channel; water is sprayed into the shell through the first tube, and the screened seeds are sent into the first tube through the second tube to be mixed with water. The mixed seeds and water are sent into the shell through the first tube; and the water spraying components in the first cavity, the second cavity and the third cavity are started to spray water vertically.

[0022] When the mixed liquid reaches the first chamber, the heavier seeds in the mixed liquid fall into the first chamber under the action of their own gravity. At the same time, the water spray assembly in the first chamber sprays water vertically. The water flow from the water spray assembly creates an upward driving force on the mixed liquid, further reducing the sedimentation rate of seeds in the mixed liquid that are not heavy enough to fall into the first chamber, so that they follow the mixed liquid into the next chamber. During the process of the mixed liquid being sprayed from the first tube into the interior of the housing, the farther the mixed liquid is from the first tube, the weaker its lateral force. The baffle also blocks the lateral movement of the mixed liquid, thereby hindering the lateral flow of the mixed liquid. In this case, when the mixed liquid reaches the second and third chambers in sequence, its flow rate decreases successively, and the sedimentation rate of the seeds gradually increases. In this case, the sedimentation rate of seeds of different weights in the sprayed water is affected, resulting in different weights or sizes of seeds falling into each chamber, thereby achieving a sorting effect. Through this sorting method, the first chamber contains mostly the heaviest seeds, the second chamber contains mostly the seeds of medium weight, and the third chamber contains mostly the lightest seeds.

[0023] Furthermore, the water spray assembly includes a fixed part, which is fixedly connected to the inner wall of the shell. A water pump is installed in the fixed part. The output shaft of the water pump is connected to a third pipe. The third pipe passes through the fixed part and extends into the channel. The end of the third pipe away from the water pump is connected to a one-way valve.

[0024] Beneficial effects: the fixed part can support the water pump; water is sprayed vertically through the third pipe, and the water flow sprayed from the third pipe forms an upward driving force on the mixed liquid, so that the sedimentation rate of the seeds in the mixed liquid that are not heavy enough to fall into the first cavity is further reduced, so that they follow the mixed liquid to the next cavity.

[0025] Furthermore, the shaking assembly includes a sieve plate, and the bottom and side walls of the sieve plate are respectively fixedly connected with a number of first springs and second springs. The end of the first spring away from the sieve plate is fixedly connected to the bottom wall of the shell, and the end of the second spring away from the sieve plate is fixedly connected to the inner side wall of the shell.

[0026] Beneficial effects: when the seeds fall onto the sieve plate, the sieve plate vibrates up and down and left and right under the action of the first spring and the second spring due to the weight of the seeds, thereby shaking the seeds on the sieve plate flat, and the shaken seeds fall onto the seedbed through the sieve holes; since the seeds on the sieve plate continue to fall down under the oscillation action of the first spring and the second spring, the gravity on the sieve plate gradually decreases, and the first spring and the second spring maintain the vibration for a certain time according to their own restoring force and vibration inertia, thereby achieving the purpose of continuously shaking the seeds on the sieve plate; the seeds on the sieve plate fall through the sieve holes at different positions, so that the seeds that fall onto the seedbed are basically evenly spread.

[0027] Furthermore, a plurality of partitions are fixedly connected in the seedbed, which divide the seedbed into a first seedling chamber, a second seedling chamber and a third seedling chamber from right to left. The first seedling chamber, the second seedling chamber and the third seedling chamber are respectively located below the first cavity, the second cavity and the third cavity.

[0028] Beneficial effects: Since the weights of seeds passing through different chambers are different, the heavier ones may be larger, fuller or more fully developed seeds, and the lighter ones may be smaller or empty seeds; therefore, the seeds falling into the first seedling chamber are of the best quality, and the germination rate of the seeds in the first seedling chamber is the highest. The germination rates of the seeds in the first, second and third seedling chambers decrease in turn. The settings of the first, second and third seedling chambers facilitate subsequent distinction, and the seeds in the first seedling chamber can be cultivated emphatically to further improve the germination rate.

[0029] Furthermore, filter plates are fixedly connected to the first seedling chamber, the second seedling chamber and the third seedling chamber.

[0030] Beneficial effect: When the amount of water passing through the channel is large, the moisture reaching the seedling chamber is also large. Therefore, filter plates are provided in the first seedling chamber, the second seedling chamber and the third seedling chamber. The filter plates can filter out excess moisture in the first seedling chamber, the second seedling chamber and the third seedling chamber to prevent moisture from accumulating in the first seedling chamber, the second seedling chamber and the third seedling chamber, causing seeds to rot, and improve the germination rate of seeds.

[0046] Example 2

[0047] The difference from the above embodiment is that: Figure 1-3 As shown, it also includes a sprout-promoting device, which includes a shell 1, a seedling bed 3 is provided below the shell 1, and the seedling bed 3 is fixedly connected to the shell 1 through a plurality of brackets 2;

[0048] The side wall of the shell 1 is connected to a first tube 6, and the top of the first tube 6 is connected to a second tube 7; the side wall of the shell 1 away from the first tube 6 is connected to a fourth tube;

[0049] A plurality of baffles 5 are welded to the bottom wall of the shell 1, and the baffles 5 divide the upper part of the shell 1 into a first cavity, a second cavity and a third cavity from right to left; a plurality of symmetrically arranged boxes 10 are welded in the first cavity, the second cavity and the third cavity, and the tops of the boxes 10 are all inclined; the gaps between adjacent boxes 10 constitute a channel; a first opening is opened on the side wall of the box 10 close to the channel, and an electric push rod 12 is installed in the box 10, and the model of the electric push rod 12 is preferably TJC-C3. The output shaft of the electric push rod 12 passes through the first opening and is coaxially fixedly connected to the arc plate 13 by bolts; when the adjacent arc plates 13 are closed, they are used to close the channel;

[0050] A water spray assembly is provided at each channel; a shaking assembly for shaking seeds is provided below the water spray assembly; a plurality of second openings for seeds to pass through are provided at the bottom of the shell 1; and the seedbed 3 is located below the plurality of second openings.

[0051] The water spray assembly includes a fixed part 11, which is welded to the inner wall of the shell 1. A water pump 9 is installed in the fixed part 11. The output shaft of the water pump 9 is connected to a third pipe 8. The third pipe 8 passes through the fixed part 11 and extends into the channel. The end of the third pipe 8 away from the water pump 9 is connected to a one-way valve.

[0052] The shaking assembly includes a sieve plate 14, and several first springs 15 and second springs (not shown in the figure) are welded to the bottom and side walls of the sieve plate 14 respectively. The end of the first spring 15 away from the sieve plate 14 is welded to the inner bottom wall of the shell 1, and the end of the second spring away from the sieve plate 14 is welded to the inner side wall of the shell 1.

[0053] Several partitions 4 are welded in the seedbed 3, which divide the seedbed 3 into the first seedling chamber, the second seedling chamber and the third seedling chamber from right to left. The first seedling chamber, the second seedling chamber and the third seedling chamber are respectively located below the first cavity, the second cavity and the third cavity.

[0054] The specific implementation process is as follows:

[0055] Spread the evenly mixed matrix on the seedbed 3; start the electric push rod 12, which pushes the two arc-shaped plates 13 to move toward each other to close the channel; spray water into the shell 1 through the first tube 6, and send the screened seeds into the first tube 6 through the second tube 7 to mix with water. The mixed seeds and water are sent into the shell 1 through the first tube 6; and start the water pumps 9 in the first cavity, the second cavity and the third cavity, so that the third tube 8 sprays water vertically.

[0056] When the mixed liquid reaches the first chamber, the heavier seeds in the mixed liquid fall into the first chamber under the action of their own gravity. At the same time, the third pipe 8 in the first chamber sprays water vertically. The water flow from the third pipe 8 creates an upward driving force on the mixed liquid, further reducing the sedimentation rate of seeds in the mixed liquid that are not heavy enough to fall into the first chamber, so that they follow the mixed liquid to the next chamber. During the process of the mixed liquid being sprayed from the first pipe 6 into the interior of the housing 1, the farther the mixed liquid is from the first pipe 6, the weaker its lateral force. The baffle 5 also blocks the lateral movement of the mixed liquid, thereby hindering the lateral flow of the mixed liquid. In this case, when the mixed liquid reaches the second and third chambers in sequence, its flow rate decreases successively, and the sedimentation rate of the seeds gradually increases. In this case, the sedimentation rate of seeds of different weights in the sprayed water is affected, resulting in different weights or sizes of seeds falling into each chamber, thereby achieving a sorting effect. Through this sorting method, the first chamber contains mostly the heaviest seeds, the second chamber contains mostly the seeds of medium weight, and the third chamber contains mostly the lightest seeds.

[0057] During the above process, light seeds may fall into the first cavity. Since light seeds have greater buoyancy, they may float on the water surface and overflow into the second cavity or the third cavity, while heavier seeds sink underwater. When the first tube 6 sprays the mixed liquid into the shell 1, most of the water is directly discharged through the fourth tube, and the overflowing water can also be discharged through the fourth tube.

[0058] Since the top of the box body 10 is inclined, it is convenient to guide the movement of seeds; when the sorting is completed, the seeds in the first cavity, the second cavity and the third cavity can be settled for a period of time, and the electric push rod 12 is started again to move the two arc plates 13 toward each other to open the channel; since the diameter of the channel is limited, the flow rate of the mixed liquid is limited. Since the seeds have a certain weight, when the channel is opened, most of the seeds settled at the bottom of the chamber are mixed with a small amount of water and fall onto the sieve plate 14, and the seeds suspended on the water surface are mostly empty shell seeds and can be ignored; when the channel is opened for a period of time, such as 10s, the electric push rod 12 is started again to move the two arc plates 13 toward each other to close the opening, and most of the water and empty shell seeds remain in the chamber.

[0059] When the seeds fall onto the sieve plate 14, the sieve plate 14 vibrates up and down and left and right under the action of the first spring 15 and the second spring due to the weight of the seeds, thereby shaking the seeds on the sieve plate 14 flat, and the shaken seeds fall onto the seedbed 3 through the sieve holes; since the seeds on the sieve plate 14 continue to fall down under the oscillation of the first spring 15 and the second spring, the gravity exerted on the sieve plate 14 gradually decreases, and the first spring 15 and the second spring maintain the vibration for a certain time according to their own restoring force and vibration inertia, thereby achieving the purpose of continuously shaking the seeds on the sieve plate 14; the seeds on the sieve plate 14 fall through the sieve holes at different positions, so that the seeds falling onto the seedbed 3 are basically evenly distributed; the water passing through the channel also falls into the seedbed 3 through the sieve holes, so that the substrate remains moist, which is convenient for seed germination.

[0060] Since the weights of the seeds passing through different chambers are different, the heavier ones may be larger, fuller, or more fully developed seeds, while the lighter ones may be smaller or empty seeds. Therefore, the seeds dropped into the first chamber are of the highest quality and have the highest germination rate. The germination rates of the seeds in the first, second, and third chambers decrease in sequence. Under the action of vibration, the seeds on the sieve plate 14 can also fall more evenly into the matrix, thereby further improving the seed germination rate. In this embodiment, the sieve holes of the sieve plate 14 corresponding to the first, second, and third chambers can be reduced in size in sequence.

[0061] Example 3

[0062] The difference from the above embodiment is that filter plates 16 are welded in the first seedling chamber, the second seedling chamber and the third seedling chamber.

[0063] The specific implementation process is as follows: when the amount of water passing through the channel is large, the moisture reaching the seedling chamber is also large. Therefore, filter plates 16 are provided in the first seedling chamber, the second seedling chamber and the third seedling chamber. The filter plates 16 can filter out excess moisture in the first seedling chamber, the second seedling chamber and the third seedling chamber to prevent moisture from accumulating in the first seedling chamber, the second seedling chamber and the third seedling chamber, causing seeds to rot, thereby improving the germination rate of seeds.
